Abstract
Zinc oxide (ZnO) brings about a rapid Friedel−Crafts acylation of a range of activated and unactivated aromatic compounds such as anisole and chlorobenzene with acid chlorides in solvent-free conditions at room temperature. The ZnO powder can be reused up to three times after simple washing with dichloromethane.

“Greener” Friedel−Crafts Acylations: A Metal- and Halogen-Free Methodology
Mark C. WilkinsonOrganic Letters2011 13 (9), 2232-2235“Greener” Friedel−Crafts Acylations: A Metal- and Halogen-Free Methodology
Mark C. WilkinsonOrganic Letters2011 13 (9), 2232-2235The utility of methanesulfonic anhydride for promoting the Friedel−Crafts acylation reaction of aryl and alkyl carboxylic acids is disclosed. This reagent allows the preparation of aryl ketones in good yield with minimal waste containing no metallic or ...

Manoj Raula, Md. Harunar Rashid, Tapas K. Paira, Enakshi Dinda and Tarun K. MandalLangmuir2010 26 (11), 8769-8782A simple solution-based method to prepare mainly flowerlike zinc oxide (ZnO) nanostructures using the ascorbate ion as a shape-directing/capping agent at relatively low temperature (ca. 30 and 60 °C) was described. However, we observed that different ...

The Structure and Energy of Oxygen Vacancy Formation in Clean and Doped, Very Thin Films of ZnO
Raj Ganesh S. Pala and Horia MetiuThe Journal of Physical Chemistry C2007 111 (34), 12715-12722The Structure and Energy of Oxygen Vacancy Formation in Clean and Doped, Very Thin Films of ZnO
Raj Ganesh S. Pala and Horia MetiuThe Journal of Physical Chemistry C2007 111 (34), 12715-12722We use density functional calculations to study the structure and the energy of formation of the surface oxygen vacancy (VO) in a free-standing, very-thin film (VTF) of ZnO and substitutionally doped ZnO VTF. We are interested in this system because the ...
